Motherboard Power Connector Types
There are three basic modern ATX power to motherboard connector configurations, a 20 pin connector, a 20 +4 pin connector, and a 24 pin connector. The 20 +4 may be used for either 20 pin connector motherboards or 24 pin connector motherboards. The first 20 pins are a consistent standard on all three configurations. Technically, even the 24 pin male power connector can be used on a 20 pin motherboard by allowing the four extra to hang off the side, given there is room (one one motherboard example a capacitor is in the way.)
